Want to stich lots of pictures together check out these bits of software.
Image Composite editor: http://research.microsoft.com/en-us/um/redmond/groups/ivm/ICE/
Adobe Photo shop 3: http://www.creativepro.com/article/auto-stitch-with-photoshop-cs3
I found Image Composite to be much betterat leveling out colours in the images yet adobe stores the files in much higher quality pictures.
Also is option of deepZoom but have not played with them yet.
